ABSTRACT:
Apparatus and method for forming sheets, comprising a pair of drums moving a belt to define a path for curing the sheets. Uncured material preferably polychloroprene, is put on the belt and squeezed between the drum and a roller to adjust the thickness of the layer. The drums rotate at a rate to permit the material to cure between the first and the second drum. Ovens cure the polychloroprene, which is removed at the second drum. The sheet has a thickness of from at least 0.004 inches to more than 0.25 inches. A plurality of sources supply material of at least two colors to form a sheet having stripes. Preferred sheets have an elongation to break of about 150% to about 1500%, a tensile strength of about 5 Mpa to about 50 Mpa and a modulus at 300% elongation of about 1 Mpa to about 10 Mpa.
